The heteropolycyclic compounds containing borole units were theoretically designed. The presence of electron deficient boron atoms results in full electron delocalization and remarkably affects their aromaticity. While molecules 1 and 2a exhibit antiaromaticity for inner rings and non-aromaticity for outer rings, 2b and 2c are completely aromatic.
理论上设计了含硼杂环的杂多环化合物。缺电子硼原子的存在导致了完全的电子离域,并显著影响了它们的芳香性。对于内环,分子 1 和 2a 表现出反芳香性,而对于外环,它们是非芳香性的;而 2b 和 2c 则是完全芳香的。
